Abstract (en)
[origin: EP0921206A1] A new austenitic stainless steel alloy is provided according to the following analysis: C: < 0,12, Si: < 1,0, Cr: 16-22, Mn: < 2,0, Ni: 8-14, Mo: < 1,0, either Ti: > 4.% by weight of C and < 0,8 or Nb: 8.% by weight of C and < 1,0, S: < 0,03, O: < 0,03, N: < 0.05, La: ≥ 0,02 and ≤ 0,11, and the remainder Fe and normally occurring impurities. The new steel is particularly suitable as super heater steel and heat exchanger steel.
